Question

An object of mass 10 kg is moving with speed 4 m/sec . what is the kinetic energy of the object

Answer 1

formula kinetic energy :- 1/2 mv^2

K.E = 1/2 . 10 . (4)^2
= 1/2 . 10 . 16
= 1/2 . 160
= 80 joule

Answer 2

Given-

mass- 10kg
velocity- 4m/sec
KE- ?

We know that-
given-
KE= 1/2mv^2
= 1/2×10×4^2
= 5×16
=80 joule
